What we make
Two lines of products
Steady State
Execution frameworks for solo operators. The Core Codex is a fixed 90-day system: pick one revenue engine, run it on preset rules, and let written kill criteria decide what happens next. The Attention Engine brief is a free, uncut section of it. Flow and Sight, software for qualifying, reviewing and analysing Core Codex runs, are in development.
Business toolkits
The Small Business Operations Toolkit: 21 ready-to-use tools for freelancers, agencies and e-commerce sellers, pre-filled with sample data so you can see how each one works.
How we work
Built on structure
- One job per product, with the rules written down so you can check them.
- No courses, no motivational content and no income guarantees. The Core Codex's revenue projections are deliberately conservative.
- Pay once and keep the files. No subscriptions, no accounts and no upsells.
- No trackers on this site: no cookies, no analytics, and even the fonts come from our own domain.
